IPrivacySettingsManager task killer

[mateor]

I currently do not ntend to add the

void killTask(in String[] packageName, int UID);

as I think we agreed to not add task killing to the core. Unless we use this elsewhere in the core I haven't seen yet?

If you need to add a task killing element to PDroid2.0 for the autopatcher, if it is easy and doesn't break between android versions, we can add it to autopatcher as a bit of a plugin, say, and automatically apply it to PDroid2.0 requesters. Although I would rather not, since I think that just one PDroid patch is best for everyone.

But we could, something like was discussed for default deny if you really need it.
